Rep. Darrell Issa (R-Calif.) has circulated a draft copy of a resolution that would hold Attorney General Eric Holder in contempt of Congress.

The 44-page measure was sent to members of the House Oversight and Government Reform Committee on Thursday in an attempt to shore up support for what would be the toughest action taken by Issa as chairman of the powerful panel.

Issa has been investigating the botched gun tracking operation Fast and Furious for more than a year and has repeatedly expressed his frustration at the Department of Justice’s lack of cooperation.
